How to extract individual characters from a string object in Objective-C ?
Example:
NSString * fooString = [NSString stringWithFormat:@
NSString * fooString = @"FOOSTRING";
NSMutableArray *list = [NSMutableArray array];
for (int i=0; i<fooString.length; i++) {
[list addObject:[fooString substringWithRange:NSMakeRange(i, 1)]];
}
NSLog(@"%@", list);
NSLog output:
(
F,
O,
O,
S,
T,
R,
I,
N,
G
)
How about
[fooString cStringUsingEncoding: NSUTF8StringEncoding];
you can also use [NSString getCharacters:(unichar array) range:(nsrange)];
you will get an easy to manipulate array.I needed it my self and found it on this link
